BURNlSHlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 892,944, dated November13, 1888.

Application filed March 14,1888. Serial No. 267,148. (No model.)

To aZZ whom it may concern.-

Be it known that I, CALEB JOSHUA BLAKELY, of Janesville, in the countyof Rock and State of Wisconsin, have invented certain new and usefulImprovements in Boot and Shoe Burnishing and Polishing Machines; and Ido hereby declare the following to be a full,clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to an improvement in boot and shoe burnishing andpolishing machines.

The nature and object of my present invention consists in the provisionof two sets of burnishing apparatus mounted on one machine and driven byone shaft, so connected thereto that they will be independent in actionwith regard to each other, and be permitted to re ciprocate and describearcs of different lengths to conduct different burnishing operations onopposite sides of the same machine.

A further object is to so construct a shoe and boot burnishing machinethat it will be bal anced in movement and prevented from jar orobjectionable vibration in its moving parts.

A further object is to provide a lamp-stand and lamps which may be usedto heat the bur nishing-tools while they are in position for use.

A further object is to furnish the rotary shaft which drives theburnishing mechanism with brushes that may be employed to polish theburnished work and be in convenient position for such a purpose.

XVith these objects in view my invention consists in the construction ofparts and their combination, in a manner that will be hereinafterdescribed, and indicated in the claims.

Referring to the drawings making a part of this specification, Figure 1is a front elevation of the machine in position for use. Fig. 2 is arear elevation of the burnishing-machine complete. Fig. 3 is a plan viewof the device. Fig. etis a cross-section in elevation ofthe machinetaken on the line at m, Fig. 3,to show the means of reciprocating theburnishers. Figs.

5 and 6 represent enlarged detail views of one of the rock-arms whichcarry the reciprocating burnishers supporting-arms. Figs. 7, 8,

9, and 10 are enlarged detail views of one rockarm, eccentric, andpitman, which drive the burnisher-tool.

For convenience in use the operating mechanism of this burnishing andpolishing machine is supported upon avertical hollow column, A, ofproper height, which is provided with a wide base, A to affordstability, the upwardly-tapering column being cut away on opposite sidesat A to lighten it, and also to permit a belt, which engages a drivingbandwheel, a, to have contact with another pulley on the main shaft ofthe machine, which will be fully described in its proper connection withother parts of the mechanism.

Within the column A, opposite the openings A, the fast and loose pulleysa are supported on a horizontal drive-shaft, A*, which also supports androtates the band-wheel a when the fast pulley a is speeded by a belt(notshown) which transmits motion and power from a proper source. Theupper end of the column A is extended laterally on each side to producea base-plate, A, on which the machinery is placed,which will now bedescribed. Two vertical bracket-stands, b b, are erected on thebase-plate A,which are of equal height and the same general form. Theseare pro vided with adjustable boxes 0 0 on their upper ends to revolublysupport the spindle B horizontally. The spindle B, just mentioned. givessupport to a pulley, of, which is secured thereon near its center oflength or in the same vertical plane with the band-wheel a, and thuspermits the belt 1 to travel properly on the faces of the wheel andpulley.

A balance-wheel, o, with a heavy rim is mounted upon the spindle B, nearto the pul ley a It, by momentum afforded, gives a smooth movement toreciprocating devices, which will be explained, and preventsobjectionable wearing motion or vibration of the whole machine when theburnishing-toois are in rapid mot-ion.

Upon the base-plate A, near its front edge,

there is an elongated cylindrical hub, B,formed 1 or secured to theplate. This hub is axially perforated for the reception of a round bar,I, which is made-to fit the bore of the hub, and is secured in placeWithin it by set-screws or 6,) which slots afford means for theadjustable attachment thereto of the pitmen G, one of which is shown inposition in Fig. 1, and both as they are connected to the arms and thedrivingeccentrics H in Fig. 3.

The eccentrics H are secured on the spindle B, near the outer ends ofthe same, so as to cause the looselyattached pitmen G to lie parallel tothe sides of the rock-arms F, to

which they are fastened by means which will be hereinafter explained.The method of connecting these parts is shown in the enlarged detailviews given in Figs. 9 and 10.

In Fig. 10, which is a top plan view of one of the rock-arms G and anattached pitman and eccentric, the end of the pitman G, which isconnected to the rock-arm F by an adj ustable stud, m, is broken intosections, thus exposing the thimble g, which is made separate but firmlyinserted in the perforated end '5 of the pitman to provide a goodwearing-surface, the thimble being made of hard brass, bronze, hardenedsteel, or any other suitable metal that may be preferred. The other endof the stud m is secured to the rock-arm F by the insertion of itsreduced and flattenedbody through the slot, to engage with the shoulderm, and be secured in this slot by a clamping-nut, or a setbolt, W, asmay be preferred.

It should be u ndcrstood that the throw of each eccentric is preferablymade the same, although this is'not imperative, as, if it is desired,they may be varied in this respect without detriment to the operation ofthe machine.

The two rock arms F and pitmen G are alike in construction, generallyspeaking, the only changes made being such as are necessary to adaptthem to be located on the right and left sides of the machine. Upon theupper ends of the rock-arms F rounded bosses F are formed, which havesquared projections p made on them to receive thereon the matingperforated ends of, the curved burnisher carrying-arms O, which are heldin place by bolts which are inserted through holes 19 made in thesquared projections 19, above mentioned.

The burnisher-arms O, which are removably secured to the-bosses of therock-arms, as has been described, are preferably curved ontwardly oneach side of the machine, with their. free ends projecting horizontallya proper height above the floor of the room in which the machine islocated, so that they will present the burnisherswhich are affixedtothese ends in convenient position for use by workmen who operate onthe machine.

The metallic polishing-tools d d are made adjustable to the outer ends.of the arms 0, which carry them, and are affixed securely bybolt-connection or other approved means, so that different forms oftools to finish the edges, shank, top,'and heel of a shoe or boot may beattached quickly and exchanged when another shape is needed. sets ofburnishing apparatus, one on each side of the machine, are distinct fromeach other, their only connection being the common support afforded bythe base-plate A, and alsoin having one source of motion and power todrive them.

The irons d, so called, are actually made of steel hardened and highlypolished, they being shaped to suit the work they are to perform, and asit is necessary that they be heated before use gas may be conducted tothesetools by flexible hose in an obvious manner, which when ignited toburn from a proper burner will by contact of its flame heat the irons atwhen this is necessary.

In some cases it may be preferred to employ a lamp instead of gas toheat the tools (I d. With this end in view I provide lamps, one for eachside of the machine, which will direct by their extended wick-tubes asuitable flame upon the irons when needed. These lamps are supportedupon bracket-plates K, that are provided with perforated bosses t, whichare placed over and upon the outer extremities of the extended ends ofthe rock-arm-supporting studs I.

The bracket-plates K may be made as shown on the right-hand side of themachinein Fig. 1, or with a deep retaining-flange, K around its edge, asshown on the left side in the same figure.

The perforated bosses I on the bracketplates K answer two purposes. Thefirst has already been indicated. The other consists in their use as aretaining-abutment for the rock-arms F, the hubs F of which are incontact with the adjacent ends of these bosses t. The other ends of theelongated hubs F of rock-arms F are secured to rock easily, but withoutobjectionable end-play, by the adj ustingnuts e e, that have threadedengagement with the studs I, as shown in Fig. 1.

Upon one or both projecting ends of the spindle B, as well as theperipheral surface of the spindleat one or both its ends, brushes D areaffixed, as shown, so that these brushes will be available for use by aworkman who is burnishing work on the irons d,these brushes, from theirconstruction, being convenient to polish any portion of the burnishedwork, or the entire shoe, if necessary.

In the drawings, Fig. 3, Ihave shown asingle brush attached to one endof shaft'B; but it is evident that a similar brush can be attached tothe opposite exposed end of said shaft.

It is evident that the two IIO It will be understood from the foregoingdescription that the changing of adjustment of the ends of the pitmen Gwill cause the rockarms F to have a greater sweep if these pitman endsare secured in the elongated slots of the rock-arms near to the hubs Fof the same, and a change of adjustment of the pitmen toward the upperends of the slots f will shorten the are of vibration given to theburnishingtools (I, so that any desired reciprocatory motion may betransmitted to the burnishingirons d d in the manner stated. It willalso be apparent that the movement of one burnishing-iron may beadjusted so that it will travel through a longer are than the other andwith increased speed per inch of surface travel, although botheccentrics are of equal throw and actuated by the same spindle. Thisfeature of my machine is of great advantage, as two workmen may beemployed at one machine, and as one operator finishes the edge or heelwith a short stroke the other party may opererate with a long quickstroke on the shank of a boot or shoe, and they may exchangepieces, sothat the work is expedited with less handling than usual in suchoperations.

It should be stated that the burnishing of top pieces at the toe andedge setting may be effectually performed on this machine by a properform of irons.

In operating the machine from the position and height given to theburnishing-irons the workman will be enabled to hold the work againsthis breast to steady it and also apply Many slight changes might be madein the details of construction of this device without a departure fromthe spirit or scope of my invenvention; hence I do not wish to confinemyself to the exact forms herein shown; but,

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is
